Food allergy is becoming increasingly common. Having an allergic reaction can be alarming, especially when you are not sure of the cause.
The Division of Allergic Diseases diagnoses and treats food allergies. The diagnosis depends on a careful examination, selective skin testing or specific IgE blood tests. Food challenge testing may be performed. Some common food allergens Mayo Clinic specialists evaluate are cow's milk, chicken eggs, legumes (peanut and soybean), and fish.
Food-allergic people and their families can also meet with a dietitian to learn about food-elimination diets to ensure proper nutrition.
